Abstract

A method for lift compensation of an item (12) which is connected to a vessel (1) by means of a rope (4) which is coiled around the rope drum (6) of a lifting device (2), the lifting device (2) being provided with a heave compensator (20), a controller (30) of the heave compensator (20) controlling the effect of the driving device (32, 34, 42) of the rope drum (6) on the basis of a heave term and a deviation term, the method comprising: - bringing a correction term into the heave compensation when, because of environmental forces, the force on the rope (4) falls outside a first limit (d, e); and - leaving the correction term out when the force on the rope (4) is within a second limit (c, f), the second limit (c, f) being equal to or different from the first limit (d, e).
